SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-mvpm-v6q4-m2pf)

medium Tenable Cloud Security Plugin ID 438945

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - SiYuan is a personal knowledge management system. Versions 3.6.0 and below render package metadata fields
 (displayName, description) using template literals without HTML escaping. A malicious package author can
 inject arbitrary HTML/JavaScript into these fields, which executes automatically when any user browses the
 Bazaar page. Because SiYuan's Electron configuration enables nodeIntegration: true with contextIsolation:
 false, this XSS escalates directly to full Remote Code Execution on the victim's operating system — with
 zero user interaction beyond opening the marketplace tab. This issue has been fixed in version 3.6.1.
 (CVE-2026-33067)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260317012524-fe4523fff2c8 or later.
